Johns Manville, a manufacturer of building products, has announced the purchase of Industrial Insulation Group (IIG), a manufacturer of insulation for industrial, commercial and fireproofing applications.

Denver-based Johns Manville joined U.S. Senators Michael Bennet and Johnny Isakson in Washington, D.C., to applaud the introduction of the Sensible Accounting to Value Energy (SAVE) Act, a bipartisan bill aimed at encouraging greater investment in insulation and other forms of home energy efficiency.
